HANDLE STRUCTURE FOR TORCH TANKS.

Application led October 7, 1927. Serial No. 224,743.v

This invention relates to handle structure for torch tanks and has to doparticularly with a novel'andextremely simple tank and handle structureso cooperating as to make a very compact, strong and inexpensivestructure. A

Heretofore in the manufacture of tanks for torches, and -similarstructures, many attempts have beenmade to provide a suitable handlestructure and method 0f securing the same to the tanks. As the tanks areusually drawn out of relatively thin sheet drawing brass, the walls arerelatively thin, and it has'been somewhat ofa problem to properly securea handle tothe tank that will be inexpensive, stand rough usage and nottend to rupture or `cause leaks 1n Ythe tank. Probably the mostsatisfactory handle structure 'for torchv tanks andthe like, has beenthe forming of two openings in the tank shelland reinforcing` theopenings with' suitable reinforcing means, and then securing the handleybymeans of two separate armsv to the reinforcing means through the twoopenings. Such a structure has given fairly satisfactory service, but itis'necessarily yexpensive both in structure and assembly features.- i

lIt is the object of the present invention to provide an extremelysimple, compact and stronghandle structure for torch tanks and the like,and which handle lstructure'is relativelyl inexpensive both as tostructure v:and assembly. vWe obtaintliis simplicity o and compactness.by providing only one lhandle opening in the tankaml utilizing a handlestructure having a metallic connecting arni formed of one piece, but Ushaped so as toit the handle. This single handle armis secured to thetank at the single point by a novel securing means so as to.

" render'the joint solid, strong and leafproof, and the handle isprevented from turning Yby stamping, or forming a suit- 0 abledepression longitudinally of the tank.

in alignment with a single opening whereby the single rU 'shaped handlearm lits closely within the depression.v ,This depression not only'reinforces the tank at Vthe point of o handle assembly,` butalsoprovides a large bearing surface around the handle arm` topositively prevent 'turning of the handle.

Invthe drawings: v

l is a fragmentary, front elevation partly. in section of a torch ktankembodying our invention and illustrating in dotted lines and solid linesthe position of the handle arm before and after assembly. y

Fig. 2 is a fragmentary sectional view illivistrating the step offorming the reinforcing nut to the inside ofthe shell-at thel presentinvention may be suitably adapted f toother tank structures presenting asimilar problemas to strength,coinpactness and rinexpensive design. i i

In Fig. l'we have illustrated a standard torch tank which may begenerally designated l, the usual burner and torch structure at the topbeing left off. This `rtank structure is preferably of the ,usuallconstruction,

being drawn out of a iatsheet of speciah deep drawing brass whereby toinakey the entire tank or shell without a seam. This is only thepreferred construction, as it will be understood that the Vtank or shellmay be made in any manner desired. of the side of the tank is stampedand otherwise suitably depressed, at 2, so :is to `form a rectangular,longitudinal depression,

the face of which is preferably arcuate and l concentric with the circular shell.

The handle for this torchV tankr is generally designated 3 and ispreferably formed ofv a.v grip and ak one piece metallic handle ele-`ment, the lowerv leg 4 being preferably longer than the upper leg 5whereby the handle grip will extend slightly lupwardly and at an angleto the axis of the torch tank.

`This one piece metallicy handle structure is thus U shaped andthe/attaching portion of the handle is preferably curved, as shown indotted lines at 6, before being secured to the torch tank. The metallic`handle structure,

as thus shown -in Fig. 4, is preferably of flat strip stock which may beeasily bent into kshapeby suitablefdies or forms, andthe A portion llonger attaching portion 6 is preferably arcuate'in cross :sectioncorrespondino to the arcuate shape of the depression@ (Ientrallypositioned in the attaching portion (Sis a tapered aperture-forreceiving a suitable attaching screw lug, or securing means.

The rectangular longitudinal depression 2 is perforated, as best shownat 8 in Fig. 2,

and the edges of this perforationare turned inwardly to form anvannularring projection. In order to tightly seal this-perforation 8, and at thesame time provide a rein- 'forcing'and attaching means for the handle,

we have 'provided a suitable attaching nut 9, which is preferably amachine screw product having an annular'recess`10 for receiv ingthe'inturned edge `off theperforation 8. A suitablering of solder ispreferablyinser'ted in the bottom of this recess l0` and the knut 9isforced through theaperture "8 until the inturned edge of the aperturepresses -the ring of solder intov the bottom of theannular depression10. The nut 9 is'alsol provided with a suitable annularv extension'llywhich is adapted to be spun over, as shown in Fig. 2, whereby torigidly secure theV nut in position. Heat is then applied lto the nutand adjacent portion of the tank whereby 'to vmelt the solder which thenfills all ythe crevthe same time drawing the portion G of the handleinto contacting relation with the sui"- faces of the depression 2. Theresiliency of portion 6 of the handle serves a lock washerfor the screw,and by drawing this curved portion 6 intoposition, it vwill also tightlyforce the edges of the portion 6 against both the top and side edges ofthe depression` 2. This will insure a very compact and non-rattlingstructure.

It will thus be seen that we have provided `a novel combination of atank and handle "structure, the handle structure itself being verysimple and inexpensive, and formed of a single strip of material, thetank being formed of a reinforcing depression and provided -with-asingle opening for receivinga single nut for securing the handle to thetank, the depression in the tank not only reinforcing the tank, but alsopreventing turning of thel handle, andthe initial arcu- 'ate' shaping ofthehandle insuring a tight,

rigid and' 'compact connection between the 'handle and the tank. Thisnovel combination not only presents a very inexpensive initial structurefor a handle structure, but applicants have 'found that "it very materially reduces the costl of assembly.

What we claim is: v

2. In combination with a torch tank having han- A a hollow shellstructure forming ai reservoir, a
